From what I know of the Apex and Flat line barrels yes they do give you the range. But they lack shot to shot consistency. As for the choices in the poll I don't use any of them. I run CMI barrels. Everyone goes on about them being too long and not efficient, But I don't care about CO2 usage when they get an excellent pattern through all the different distances that I shoot. That and for the MilSim look they are great too.
